I like many others are having problems with my ATI card (X800XT in my case) and the 15.9.3 patch it seems. The symptom you will see is that randomly your AO client will just fold and drop you back to desktop. If you are unlucky this will result in one or more of your toons stuck in a crash loop
For fellow sufferers I just wanted to let you know there has been some good discussion over on the Tech Help forum and some suggestions about possible work arounds:
Option A (from Marzaii): download an old DNA driver version 3.0.4.9 : http://downloads.guru3d.com/download.php?det=865 Of course you might not want those drivers for any other games you play
Option B (from Prikje): in the AO start up screen select D3D HAL mode - unfortunately you will take a big fps hit for not using the hardware T&L
[EDIT June 3rd added option C]
Option C (from dodger6): try the latest Omega drivers : http://www.omegadrivers.net/ these are based on the 5.4 catalyst drivers so pretty current
[EDIT June 27 added option D]
Option D - 4.12 catalyst drivers seem to be safe and stable for all ATI users previously reporting AO problems - of course they are old drivers and you will miss all the recent performance enhancements of the newer drivers You can get the 4.12 drivers by looking in the old drivers section on the ATI website - an alternative direct link is : http://drivers.softpedia.com/get/GRA...lyst-412.shtml
